1Score steak on both sides; place in large resealable food-storage plastic bag or ungreased 13x9-inch (3-quart) glass baking dish.
2In medium bowl, mix remaining ingredients; spoon over steak. Seal bag or cover baking dish with plastic wrap. Let stand at room temperature 15 minutes.
3Set oven control to broil. Spray broiler pan with cooking spray. Place steak on pan; brush with liquid from bag or dish. Reserve tomatoes. Broil with top of steak 4 to 6 inches from heat 10 to 15 minutes or until steak is desired doneness, turning once.
4With slotted spoon, spoon tomatoes onto steak; discard remaining liquid. Broil 3 to 5 minutes longer until tomatoes are lightly browned. Cut steak diagonally across grain into thin slices to serve.
